However I noticed that there has been a problem lately with how items were added to one transaction. It looks like this:

It made the report twice the amount of the actual products purchased (I knew this because I used Ecwid as our eCommerce platform and could easily compare the transaction there).

I want to ask if you have any ideas on how or why this happens. There's one other strange thing that this kind of behaviour didn't happen before 7th of March; the date didn't mean anything in specific, we made some changes that day too but nothing related to this function - it just to implicates that it has not always been the case.
